Description

本発明は、電気回路を開閉する電磁継電器およびその製造方法に関する。 The present invention relates to an electromagnetic relay that opens and closes an electric circuit and a manufacturing method thereof .

特許文献１に示された従来の電磁継電器は、励磁コイルへの通電により可動板と固定コアとの対向面間に電磁吸引力が発生し、その電磁吸引力により可動板が固定コア側に吸引されるようになっている。   In the conventional electromagnetic relay disclosed in Patent Document 1, an electromagnetic attractive force is generated between the opposed surfaces of the movable plate and the fixed core by energizing the exciting coil, and the movable plate is attracted to the fixed core side by the electromagnetic attractive force. It has come to be.

そして、励磁コイルの外周側および励磁コイルの軸方向両端を覆うヨークは、１枚の板材を折り曲げて構成され、励磁コイルの軸方向一端側に位置して可動板に対向するフランジ部と、励磁コイルの軸方向他端側に位置する底板部と、励磁コイルの外周側に位置する筒部とを備えている。   The yoke that covers the outer periphery of the excitation coil and both ends of the excitation coil in the axial direction is formed by bending a single plate, and is positioned on one end in the axial direction of the excitation coil and facing the movable plate, and the excitation A bottom plate portion located on the other axial end side of the coil and a cylindrical portion located on the outer peripheral side of the exciting coil are provided.

また、フランジ部は、１枚の板材の両端にそれぞれ形成されており、可動板側から見たときには分割された形状になっている。   The flange portions are respectively formed at both ends of a single plate material, and have a divided shape when viewed from the movable plate side.

さらに、可動板とヨークとの間に非磁性体よりなる板が介在されている。そして、コイル通電時の可動板の移動範囲がこの板により規制されることにより、コイル通電時に可動板はヨークおよび固定コアの何れにも当接しないようになっている。すなわち、コイル通電時に、可動板とヨークとの間にエアギャップが形成されると共に、可動板と固定コアとの間にエアギャップが形成される。   Further, a plate made of a non-magnetic material is interposed between the movable plate and the yoke. The moving range of the movable plate when the coil is energized is restricted by this plate, so that the movable plate does not come into contact with either the yoke or the fixed core when the coil is energized. That is, when the coil is energized, an air gap is formed between the movable plate and the yoke, and an air gap is formed between the movable plate and the fixed core.

特開２０１２−５４０４８号公報JP 2012-54048 A

しかしながら、従来の電磁継電器におけるヨークは、１枚の板材を折り曲げて構成されるため、プレス加工が容易ではない。   However, a yoke in a conventional electromagnetic relay is configured by bending a single plate material, so that pressing is not easy.

また、フランジ部は１枚の板材の両端に形成されるため、一方のフランジ部における可動板に対向する面のコイル軸方向位置と、他方のフランジ部における可動板に対向する面のコイル軸方向位置の、ずれが発生しやすい。したがって、一方のフランジ部と可動板との距離と、他方のフランジ部と可動板との距離の、ばらつきが大きくなり、ひいては電磁吸引力のばらつきが大きくなってしまう。   Further, since the flange portion is formed at both ends of one plate member, the coil axial direction position of the surface facing the movable plate in one flange portion and the coil axial direction of the surface facing the movable plate in the other flange portion Misalignment is likely to occur. Therefore, the variation in the distance between the one flange portion and the movable plate and the distance between the other flange portion and the movable plate increase, and as a result, the variation in the electromagnetic attractive force increases.

さらに、エアギャップ寸法はばらつきやすいため、電磁吸引力のばらつきが大きくなってしまう。   Furthermore, since the air gap dimension is likely to vary, the electromagnetic attraction force varies greatly.

本発明は上記点に鑑みて、ヨークのプレス加工を容易にし、且つ、電磁吸引力のばらつきを小さくすることを目的とする。   The present invention has been made in view of the above points, and it is an object of the present invention to facilitate yoke pressing and reduce variations in electromagnetic attraction force.

上記目的を達成するため、請求項１に記載の発明では、通電時に磁界を形成する励磁コイル（１２）と、励磁コイルの内部に配置され、磁気回路を構成する柱状の固定コア（１３）と、励磁コイルの外周側および励磁コイルの軸方向両端を覆うように配置され、磁気回路を構成するヨーク（１４、１５）と、励磁コイルの軸方向一端側に配置され、励磁コイルへの通電時に固定コア側に吸引される板状の可動板（１６）とを備える電磁継電器において、ヨークは、複数の板材にて構成され、複数の板材は、励磁コイルの軸方向一端側を覆って可動板に対向するヨーク対向板部を含む第１板材（１５）と、励磁コイルの軸方向他端側を覆う部位を含む第２板材（１４）とを備え、可動板は、励磁コイルへの通電時に、固定コアおよびヨーク対向板部のうちヨーク対向板部のみに当接することを特徴とする。 In order to achieve the above object, according to the first aspect of the present invention, an exciting coil (12) that forms a magnetic field when energized, a columnar fixed core (13) that is disposed inside the exciting coil and constitutes a magnetic circuit; It is arranged so as to cover the outer peripheral side of the excitation coil and both ends in the axial direction of the excitation coil, and is arranged on one end side in the axial direction of the excitation coil and the yoke (14, 15) constituting the magnetic circuit. In an electromagnetic relay including a plate-like movable plate (16) attracted to the fixed core side, the yoke is composed of a plurality of plate materials, and the plurality of plate materials cover one end side in the axial direction of the exciting coil and are movable plates. And a second plate member (14) including a portion covering the other axial end of the exciting coil. The movable plate is configured to energize the exciting coil. , Opposed to fixed core and yoke Wherein the contact only to the yoke facing plate portion of the section.

これによると、ヨークを複数の板材にて構成するため、ヨークを１枚の板材で構成する場合よりも、プレス加工が容易である。   According to this, since the yoke is composed of a plurality of plate materials, press working is easier than in the case where the yoke is composed of a single plate material.

また、ヨーク対向板部は、可動板側から見たときに分割された形状になっていないため、換言すると、１枚もので連続しているため、従来のような、一方のフランジ部における可動板に対向する面のコイル軸方向位置と、他方のフランジ部における可動板に対向する面のコイル軸方向位置の、ずれが発生するという問題が発生しない。したがって、電磁吸引力のばらつきが小さくなる。   Further, since the yoke-facing plate portion is not divided when viewed from the movable plate side, in other words, since it is continuous with a single piece, it can be moved at one flange portion as in the prior art. There is no problem that a deviation occurs between the position in the coil axis direction of the surface facing the plate and the position in the coil axis direction of the surface facing the movable plate in the other flange portion. Therefore, the variation in electromagnetic attractive force is reduced.

また、励磁コイルへの通電時に可動板とヨーク対向板部との間にエアギャップは形成されないため、従来のような、エアギャップ寸法のばらつきによる電磁吸引力のばらつきは発生しない。 In addition , since no air gap is formed between the movable plate and the yoke-facing plate when the exciting coil is energized, there is no variation in electromagnetic attraction force due to variation in the air gap size as in the prior art.

また、励磁コイルへの通電時に可動板が固定コアおよびヨーク対向板部のうち固定コアのみに当接する構成であると、励磁コイルへの通電時に可動板が固定コアに衝突した衝撃で可動板が傾いて、可動板がヨーク対向板部に当接する場合がある。そして、可動板がヨーク対向板部に当接すると吸引力が増加するため、可動板がヨーク対向板部に当接する場合と当接しない場合とで吸引力がばらついてしまう。   Further, if the movable plate is in contact with only the fixed core of the fixed core and the yoke-facing plate portion when the excitation coil is energized, the movable plate is moved by the impact of the movable plate colliding with the fixed core when the excitation coil is energized. In some cases, the movable plate abuts against the yoke-facing plate portion. Since the suction force increases when the movable plate comes into contact with the yoke facing plate portion, the suction force varies depending on whether the movable plate is in contact with the yoke facing plate portion or not.

これに対し、励磁コイルへの通電時に可動板がヨーク対向板部に当接する構成にすると、励磁コイルへの通電時に可動板がヨーク対向板部に衝突しても可動板は傾かないため、可動板が固定コアに当接せず、電磁吸引力のばらつきが小さくなる。   On the other hand, if the movable plate abuts against the yoke-facing plate when energizing the exciting coil, the movable plate will not tilt even if the movable plate collides with the yoke-facing plate when energizing the exciting coil. The plate does not come into contact with the fixed core, and variations in electromagnetic attraction force are reduced.

請求項２に記載の発明のように、請求項１に記載の電磁継電器において、第１板材が励磁コイルの外周側を覆う部位を含むようにしてもよいし、請求項３に記載の発明のように、第２板材が励磁コイルの外周側を覆う部位を含むようにしてもよい。 As in the invention according to claim 2 , in the electromagnetic relay according to claim 1 , the first plate member may include a portion covering the outer peripheral side of the exciting coil, or as in the invention according to claim 3. The second plate may include a portion that covers the outer peripheral side of the exciting coil.

請求項４に記載の発明は、請求項１ないし３のいずれか１つに記載の電磁継電器を製造する方法であって、電磁継電器は、ヨークが一体的に組み付けられるとともに、脱着可能なスペーサが通過するスペーサ通し部（２０４）が形成されたベース（２０）を備え、可動板とヨーク対向板部との間にスペーサを挟持させた状態で、ベースに対するヨークの位置決めを行うとともに、スペーサを、スペーサ通し部（２０４）を通過させて可動板とヨーク対向板部との間に抜き差しすることを特徴とする。 A fourth aspect of the present invention is a method for manufacturing the electromagnetic relay according to any one of the first to third aspects, wherein the electromagnetic relay has a yoke integrally assembled and a removable spacer. A base (20) having a spacer passage portion (204) passing therethrough is provided, and the yoke is positioned with respect to the base in a state where the spacer is sandwiched between the movable plate and the yoke facing plate portion, It is characterized by being inserted and removed between the movable plate and the yoke-facing plate portion through the spacer passage portion (204) .

これによると、スペーサの抜き差しを容易に行うことができる。   According to this, the spacer can be easily inserted and removed.

以下、本発明の実施形態について図に基づいて説明する。なお、以下の各実施形態相互において、互いに同一もしくは均等である部分には、図中、同一符号を付してある。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, the same or equivalent parts are denoted by the same reference numerals in the drawings.

（第１実施形態）
本発明の第１実施形態について説明する。 (First embodiment)
A first embodiment of the present invention will be described.

図１〜図３、および図７に示すように、樹脂製のケース１１内には、通電時に磁界を形成する円筒状の励磁コイル１２が配置されている。励磁コイル１２の径方向中心部の孔には、磁性体金属材料よりなる固定コア１３が配置されている。固定コア１３は、励磁コイル１２の中心部孔に挿入される円柱状のコア軸部１３１、および励磁コイル１２の外部に位置しコア軸部１３１よりも大径の円柱状のコア鍔部１３２を備えている。   As shown in FIGS. 1 to 3 and 7, a cylindrical excitation coil 12 that forms a magnetic field when energized is disposed in a resin case 11. A fixed core 13 made of a magnetic metal material is disposed in the hole in the central portion of the exciting coil 12 in the radial direction. The fixed core 13 includes a cylindrical core shaft portion 131 inserted into the central hole of the exciting coil 12 and a cylindrical core flange portion 132 positioned outside the exciting coil 12 and having a larger diameter than the core shaft portion 131. I have.

磁性体金属材料よりなる板材を略Ｕ字状に折り曲げた第２板材１４により、励磁コイル１２の外周側および励磁コイル１２の軸方向一端側が覆われている。   The outer peripheral side of the exciting coil 12 and the one end side in the axial direction of the exciting coil 12 are covered by a second plate member 14 obtained by bending a plate made of a magnetic metal material into a substantially U shape.

磁性体金属材料よりなる矩形平板状の第１板材１５により、励磁コイル１２の軸方向他端側が覆われている。また、第１板材１５は、後述する可動板１６に対向している。なお、第１板材１５は、本発明のヨーク対向板部に相当する。   The other end side in the axial direction of the exciting coil 12 is covered with a rectangular plate-shaped first plate member 15 made of a magnetic metal material. Further, the first plate member 15 is opposed to a movable plate 16 described later. The first plate material 15 corresponds to the yoke facing plate portion of the present invention.

第１板材１５には、中心部に貫通したヨーク孔１５１が形成されており、このヨーク孔１５１内にコア鍔部１３２が配置されている。固定コア１３と第２板材１４が接合され、第２板材１４と第１板材１５が接合されている。なお、第２板材１４および第１板材１５は、本発明のヨークを構成している。   A yoke hole 151 is formed in the first plate member 15 so as to penetrate through the central portion, and the core flange 132 is disposed in the yoke hole 151. The fixed core 13 and the second plate member 14 are joined, and the second plate member 14 and the first plate member 15 are joined. In addition, the 2nd board | plate material 14 and the 1st board | plate material 15 comprise the yoke of this invention.

このように、ヨークを複数の板材にて構成することにより、ヨークを１枚の板材で構成する場合よりも、プレス加工が容易になる。   In this way, by forming the yoke with a plurality of plate members, press working becomes easier than when the yoke is formed with a single plate member.

コア鍔部１３２および第１板材１５に対向する位置には、磁性体金属材料よりなる板状の可動板１６が配置されている。換言すると、可動板１６は、固定コア１３および第１板材１５に対向している。なお、固定コア１３、第２板材１４、第１板材１５、および可動板１６は、励磁コイル１２により誘起された磁束の磁気回路を構成する。   A plate-shaped movable plate 16 made of a magnetic metal material is disposed at a position facing the core flange 132 and the first plate member 15. In other words, the movable plate 16 faces the fixed core 13 and the first plate material 15. Note that the fixed core 13, the second plate member 14, the first plate member 15, and the movable plate 16 constitute a magnetic circuit of magnetic flux induced by the exciting coil 12.

励磁コイル１２と可動板１６との間には、可動板１６を反固定コア側に付勢する復帰ばね１７が配置されている。そして、励磁コイル１２への通電により、可動板１６は電磁吸引力により復帰ばね１７に抗して固定コア１３側に吸引される。   Between the exciting coil 12 and the movable plate 16, a return spring 17 that urges the movable plate 16 toward the anti-fixed core is disposed. When the excitation coil 12 is energized, the movable plate 16 is attracted toward the fixed core 13 against the return spring 17 by electromagnetic attraction force.

可動板１６には、金属製のシャフト１８が結合されている。より詳細には、可動板１６の中心部に形成された可動板孔１６１にシャフト１８が挿入され、シャフト１８の一端に形成されたシャフト鍔部１８１と、シャフト１８に嵌合された第１止め輪１９とによって、可動板１６とシャフト１８が結合されている。   A metal shaft 18 is coupled to the movable plate 16. More specifically, the shaft 18 is inserted into the movable plate hole 161 formed at the center of the movable plate 16, and the shaft collar 181 formed at one end of the shaft 18 and the first stop fitted to the shaft 18. The movable plate 16 and the shaft 18 are coupled by the wheel 19.

なお、可動板１６とシャフト１８は、シャフト１８の径方向および軸方向に相対移動可能なように、所定のガタを持って結合されている。このように、ガタを持たせることにより、可動板１６が固定コア１３側に吸引された際に、可動板１６を第１板材１５に確実に接触させることができる。   The movable plate 16 and the shaft 18 are coupled with a predetermined backlash so as to be relatively movable in the radial direction and the axial direction of the shaft 18. In this way, by providing play, the movable plate 16 can be reliably brought into contact with the first plate member 15 when the movable plate 16 is attracted to the fixed core 13 side.

シャフト１８は、その中間部が樹脂製のベース２０に摺動自在に挿入されている。シャフト１８におけるベース２０から突出した部位には、第２止め輪２１が嵌合されるとともに、導電金属製の板状の可動子２２が摺動自在に装着されている。   An intermediate portion of the shaft 18 is slidably inserted into the resin base 20. A portion of the shaft 18 protruding from the base 20 is fitted with a second retaining ring 21 and a conductive metal plate-like movable element 22 is slidably mounted.

シャフト１８の他端に嵌合された第３止め輪２３と可動子２２との間には、可動子２２を固定コア１３側（すなわち、第２止め輪２１側）に付勢する接圧ばね２４が配置されている。可動子２２には、導電金属製の可動接点２５が２個かしめ固定されている。   A contact pressure spring that biases the mover 22 toward the fixed core 13 (that is, the second stop ring 21 side) between the third retaining ring 23 fitted to the other end of the shaft 18 and the movable element 22. 24 is arranged. Two movable contacts 25 made of conductive metal are fixed to the movable element 22 by caulking.

導電金属製の板状の第１固定端子２６に、導電金属製の第１固定接点２７がかしめ固定され、導電金属製の板状の第２固定端子２８に、導電金属製の第２固定接点２９がかしめ固定されている。   A first fixed contact 27 made of conductive metal is caulked and fixed to the first fixed terminal 26 made of conductive metal, and a second fixed contact made of conductive metal is fixed to the second fixed terminal 28 made of conductive metal. 29 is fixed by caulking.

第１固定端子２６および第２固定端子２８は、ベース２０に固定されている。第１固定接点２７は一方の可動接点２５に対向して配置され、第２固定接点２９は他方の可動接点２５に対向して配置されている。   The first fixed terminal 26 and the second fixed terminal 28 are fixed to the base 20. The first fixed contact 27 is disposed to face one movable contact 25, and the second fixed contact 29 is disposed to face the other movable contact 25.

そして、可動子２２および可動接点２５が可動板１６に追従して移動し、それにより可動接点２５が第１固定接点２７および第２固定接点２９と接離して、第１固定接点２７と第２固定接点２９との間が電気的に導通または遮断されるようになっている。   Then, the movable element 22 and the movable contact 25 move following the movable plate 16, whereby the movable contact 25 comes in contact with and separates from the first fixed contact 27 and the second fixed contact 29, and the first fixed contact 27 and the second fixed contact 27. The fixed contact 29 is electrically connected or disconnected.

図３、図８に示すように、ベース２０は、平板状の基板部２０１、基板部２０１に対して垂直でシャフト１８が挿入される第１保持板部２０２、可動板移動方向に沿って延びる第２保持板部２０３を備えている。第１保持板部２０２には、後述するスペーサが通過するスペーサ通し部としての切欠き部２０４が形成されている。第２保持板部２０３には、第２板材１４の端部が挿入される溝２０５が形成されている。そして、第２板材１４の端部を溝２０５に圧入して固定することにより、第２板材１４がベース２０に一体的に組み付けられる。   As shown in FIGS. 3 and 8, the base 20 extends along the plate-shaped substrate portion 201, the first holding plate portion 202 into which the shaft 18 is inserted perpendicular to the substrate portion 201, and the movable plate moving direction. A second holding plate portion 203 is provided. The first holding plate portion 202 is formed with a notch portion 204 as a spacer passage portion through which a spacer described later passes. The second holding plate portion 203 is formed with a groove 205 into which the end portion of the second plate member 14 is inserted. And the 2nd board | plate material 14 is integrally assembled | attached to the base 20 by press-fitting and fixing the edge part of the 2nd board | plate material 14 in the groove | channel 205.

The inner diameter of the movable plate second plate portion 165 is larger than the outer diameter of the core flange portion 132, and when the movable plate 16 is attracted to the fixed core 13 side by electromagnetic attraction force, the movable plate second plate. The core flange 132 enters the inner space of the portion 165.

可動板第２対向面１６４は、可動板移動方向に対して非垂直な面であり、より詳細には、可動板移動方向と略平行に延びる面である。したがって、可動板第１対向面１６２と可動板第２対向面１６４とのなす角は略９０°になっている。そして、可動板第１対向面１６２と可動板第２対向面１６４とのなす角を９０°以上にすることにより、可動板１６をプレス加工により形成する場合、その加工を容易に行うことができる。   The movable plate second facing surface 164 is a surface that is non-perpendicular to the movable plate moving direction, and more specifically, is a surface that extends substantially parallel to the movable plate moving direction. Therefore, the angle formed by the movable plate first opposing surface 162 and the movable plate second opposing surface 164 is approximately 90 °. When the movable plate 16 is formed by press working by making the angle formed by the movable plate first facing surface 162 and the movable plate second facing surface 164 90 ° or more, the processing can be easily performed. .

また、固定コア第２対向面１３４と可動板第２対向面１６４は、可動板移動方向に沿って見たときに重ならないように配置されている。   Further, the fixed core second facing surface 134 and the movable plate second facing surface 164 are arranged so as not to overlap when viewed along the movable plate moving direction.

可動板１６は、可動板第２板部１６５の先端部から折り曲げられて、通電遮断時移動向きＣおよび外側に向かって延びる可動板第３板部１６６を備えている。そして、可動板１６が電磁吸引力により固定コア１３側に吸引された際に、可動板第２板部１６５および可動板第３板部１６６がヨーク孔１５１内に侵入するようになっている。   The movable plate 16 includes a movable plate third plate portion 166 that is bent from the distal end portion of the movable plate second plate portion 165 and extends toward the movement direction C when energization is cut off and toward the outside. The movable plate second plate portion 165 and the movable plate third plate portion 166 enter the yoke hole 151 when the movable plate 16 is attracted to the fixed core 13 side by electromagnetic attraction force.

可動板１６は、可動板第３板部１６６の先端部から折り曲げられて、可動板移動方向に対して略垂直な方向に延びる可動板第４板部１６７を備えている。この可動板第４板部１６７は、第１板材１５に対向している。   The movable plate 16 includes a movable plate fourth plate portion 167 that is bent from the distal end portion of the movable plate third plate portion 166 and extends in a direction substantially perpendicular to the movable plate moving direction. The movable plate fourth plate portion 167 faces the first plate material 15.

そして、可動板１６は、電磁吸引力により固定コア１３側に吸引された際に、固定コア３には当接せず、第１板材１５におけるヨーク孔１５１の周囲に当接するようになっている。   When the movable plate 16 is attracted to the fixed core 13 side by electromagnetic attraction force, the movable plate 16 does not contact the fixed core 3 but contacts the periphery of the yoke hole 151 in the first plate material 15. .

ここで、ヨーク対向板部である第１板材１５は、可動板１６側から見たときに分割された形状になっていないため、換言すると、１枚もので連続しているため、従来のような、一方のフランジ部における可動板に対向する面のコイル軸方向位置と、他方のフランジ部における可動板に対向する面のコイル軸方向位置の、ずれが発生するという問題が発生しない。したがって、電磁吸引力のばらつきが小さくなる。   Here, since the first plate member 15 which is the yoke-facing plate portion is not divided when viewed from the movable plate 16 side, in other words, it is continuous by one piece, so that it is conventional. In addition, there is no problem that a deviation occurs between the position in the coil axis direction of the surface facing the movable plate in one flange portion and the position in the coil axis direction of the surface facing the movable plate in the other flange portion. Therefore, the variation in electromagnetic attractive force is reduced.

また、第１板材１５は１枚もので連続しているため、第１板材１５と可動板１６との対向面積が増加し、電磁吸引力が増加する。   Moreover, since the 1st board | plate material 15 is continuing by one piece, the opposing area of the 1st board | plate material 15 and the movable plate 16 increases, and electromagnetic attraction force increases.

次に、本実施形態に係る電磁継電器の作動を説明する。   Next, the operation of the electromagnetic relay according to this embodiment will be described.

まず、励磁コイル１２への通電が遮断されると、可動板１６やシャフト１８や可動子２２が復帰ばね１７により通電遮断時移動向きＣに駆動される。これにより、可動接点２５が第１固定接点２７および第２固定接点２９から離れて、第１固定接点２７と第２固定接点２９との間が電気的に遮断状態となる（図１参照）。   First, when the energization to the exciting coil 12 is cut off, the movable plate 16, the shaft 18 and the mover 22 are driven by the return spring 17 in the moving direction C when the energization is cut off. Thus, the movable contact 25 is separated from the first fixed contact 27 and the second fixed contact 29, and the first fixed contact 27 and the second fixed contact 29 are electrically disconnected (see FIG. 1).

ここで、金属製の可動板１６は樹脂製のベース２０に衝突して停止する。したがって、金属部品同士の衝突による耳障りな高周波の衝突音は発生しない。また、可動板１６は通電遮断時移動向きＣに移動する際に空気抵抗を受けて速度が減衰されるため、可動板１６とベース２０との衝突音を低減することができる。さらに、可動板１６の剛性がアップするため、可動板１６の振動が抑制され、可動板１６とベース２０との衝突音を低減することができる。   Here, the metal movable plate 16 collides with the resin base 20 and stops. Therefore, no harsh high-frequency collision sound due to collision between metal parts is generated. In addition, since the movable plate 16 receives air resistance when the movable plate 16 moves in the movement direction C when the energization is interrupted, the velocity is attenuated, so that the collision sound between the movable plate 16 and the base 20 can be reduced. Further, since the rigidity of the movable plate 16 is increased, the vibration of the movable plate 16 is suppressed, and the collision sound between the movable plate 16 and the base 20 can be reduced.

一方、励磁コイル１２に通電すると、可動板１６が電磁吸引力により復帰ばね１７に抗して固定コア１３側に吸引され、シャフト１８や可動子２２が可動板１６に追従して通電開始時移動向きＢに移動し、それにより可動接点２５が第１固定接点２７および第２固定接点２９に当接して、第１固定接点２７と第２固定接点２９との間が電気的に導通状態となる（図２参照）。   On the other hand, when the excitation coil 12 is energized, the movable plate 16 is attracted to the fixed core 13 side against the return spring 17 by the electromagnetic attractive force, and the shaft 18 and the mover 22 follow the movable plate 16 and move when energization starts. The movable contact 25 is brought into contact with the first fixed contact 27 and the second fixed contact 29 so that the first fixed contact 27 and the second fixed contact 29 are electrically connected. (See FIG. 2).

ここで、可動板１６は通電開始時移動向きＢに移動する際に空気抵抗を受けて速度が減衰されるため、可動板１６と第１板材１５との衝突音を低減することができる。また、可動板１６の剛性がアップするため、可動板１６の振動が抑制され、可動板１６と第１板材１５との衝突音を低減することができる。   Here, since the movable plate 16 receives air resistance when moving in the movement direction B at the start of energization and the speed is attenuated, the collision sound between the movable plate 16 and the first plate member 15 can be reduced. Further, since the rigidity of the movable plate 16 is increased, the vibration of the movable plate 16 is suppressed, and the collision sound between the movable plate 16 and the first plate member 15 can be reduced.

ところで、電磁吸引力は、対向面積に比例し、エアギャップの２乗に反比例する。ここで、固定コア第１対向面１３３と可動板第１対向面１６２とのエアギャップを第１エアギャップＬ１とし、固定コア第２対向面１３４と可動板第２対向面１６４とのエアギャップを第２エアギャップＬ２とすると、図５に示すように、励磁コイル１２への通電が遮断されている状態、すなわち、可動板１６が固定コア１３から最も離れた位置にあるときには、Ｌ１＞Ｌ２に設定されている。また、固定コア第１対向面１３３と可動板第１対向面１６２との対向面積をＳ１、固定コア第２対向面１３４と可動板第２対向面１６４との対向面積をＳ２とすると、Ｓ１／Ｌ１2＜Ｓ２／Ｌ２2の関係になっている。 Incidentally, the electromagnetic attractive force is proportional to the facing area and inversely proportional to the square of the air gap. Here, the air gap between the fixed core first facing surface 133 and the movable plate first facing surface 162 is defined as a first air gap L1, and the air gap between the fixed core second facing surface 134 and the movable plate second facing surface 164 is defined as an air gap. When the second air gap L2 is set, as shown in FIG. 5, when the energization to the exciting coil 12 is interrupted, that is, when the movable plate 16 is at a position farthest from the fixed core 13, L1> L2. Is set. Further, when the facing area between the fixed core first facing surface 133 and the movable plate first facing surface 162 is S1, and the facing area between the fixed core second facing surface 134 and the movable plate second facing surface 164 is S2, S1 / The relationship is L1 2 <S2 / L2 2 .

したがって、励磁コイル１２への通電が開始された直後、すなわち吸引開始時には、Ｌ１＞Ｌ２であるため、磁束は固定コア第２対向面１３４と可動板第２対向面１６４との間を主に通り、固定コア第２対向面１３４と可動板第２対向面１６４との間に大きな電磁吸引力が発生する。そして、その電磁吸引力を受けて可動板１６は通電開始時移動向きＢに移動し始める。   Therefore, immediately after the energization of the exciting coil 12 is started, that is, at the start of attraction, L1> L2, so that the magnetic flux mainly passes between the fixed core second opposing surface 134 and the movable plate second opposing surface 164. A large electromagnetic attraction force is generated between the fixed core second facing surface 134 and the movable plate second facing surface 164. Then, the movable plate 16 starts to move in the movement direction B at the start of energization in response to the electromagnetic attraction force.

吸引途中でＬ１≒（Ｓ１／Ｓ２）1/2×Ｌ２に近づくと、固定コア第１対向面１３３と可動板第１対向面１６２との間に発生する電磁吸引力が次第に大きくなり、その電磁吸引力を受けて可動板１６は通電開始時移動向きＢにさらに移動する。 When L1≈ (S1 / S2) 1/2 × L2 is approached during suction, the electromagnetic attractive force generated between the fixed core first opposing surface 133 and the movable plate first opposing surface 162 gradually increases, and the electromagnetic In response to the suction force, the movable plate 16 further moves in the moving direction B at the start of energization.

吸引完了時、すなわち、図６に示すように可動板１６が第１板材１５に当接して可動板１６が固定コア１３に最も近づいた位置にあるときには、Ｌ１＜Ｌ２となる。これにより、磁束は、固定コア第１対向面１３３と可動板第１対向面１６２との間を主に通り、固定コア第２対向面１３４と可動板第２対向面１６４との間は殆ど通らないため、サイドフォースは殆ど発生しない。   When suction is completed, that is, as shown in FIG. 6, when the movable plate 16 is in contact with the first plate member 15 and the movable plate 16 is in the position closest to the fixed core 13, L1 <L2. Thereby, the magnetic flux mainly passes between the fixed core first opposing surface 133 and the movable plate first opposing surface 162, and hardly passes between the fixed core second opposing surface 134 and the movable plate second opposing surface 164. Because there is no side force, almost no side force is generated.

また、吸引完了時に可動板１６と第１板材１５との間にエアギャップは形成されないため、従来のような、エアギャップ寸法のばらつきによる電磁吸引力のばらつきは発生しない。   Further, since the air gap is not formed between the movable plate 16 and the first plate member 15 when the suction is completed, there is no variation in electromagnetic attraction force due to the variation in the air gap size as in the prior art.

さらに、励磁コイル１２への通電時に可動板１６が固定コア１３および第１板材１５のうち固定コア１３のみに当接する構成であると、励磁コイル１２への通電時に可動板１６が固定コア１３に衝突した衝撃で可動板１６が傾いて、可動板１６が第１板材１５に当接する場合がある。そして、可動板１６が第１板材１５に当接すると吸引力が増加するため、可動板１６が第１板材１５に当接する場合と当接しない場合とで吸引力がばらついてしまう。   Furthermore, when the movable plate 16 is in contact with only the fixed core 13 of the fixed core 13 and the first plate member 15 when the excitation coil 12 is energized, the movable plate 16 contacts the fixed core 13 when the excitation coil 12 is energized. In some cases, the movable plate 16 is tilted by the impact, and the movable plate 16 comes into contact with the first plate member 15. Since the suction force increases when the movable plate 16 contacts the first plate member 15, the suction force varies depending on whether the movable plate 16 contacts the first plate member 15 or not.

これに対し、励磁コイル１２への通電時に可動板１６が第１板材１５に当接する構成にすると、励磁コイル１２への通電時に可動板１６が第１板材１５に衝突しても可動板１６は傾かないため、可動板１６が固定コア１３に当接せず、電磁吸引力のばらつきが小さくなる。   On the other hand, when the movable plate 16 is in contact with the first plate member 15 when the excitation coil 12 is energized, the movable plate 16 does not move even if the movable plate 16 collides with the first plate member 15 when the excitation coil 12 is energized. Since it does not tilt, the movable plate 16 does not come into contact with the fixed core 13 and variation in electromagnetic attraction force is reduced.

次に、図３、図８に基づいて、ベース２０に対する第２板材１４および第１板材１５の可動板移動方向の位置決め調整について説明する。   Next, the positioning adjustment of the second plate member 14 and the first plate member 15 in the moving plate moving direction with respect to the base 20 will be described with reference to FIGS.

ベース２０に対する第２板材１４および第１板材１５の可動板移動方向の位置決め調整は、ケース１１がない状態で行われる。まず、所定の厚さの板状のスペーサを、切欠き部２０４を通して、可動板１６における可動板第４板部１６７（図６参照）と第１板材１５との間に挿入する。なお、図８には、スペーサが挿入される部位を、便宜的に斜線で示している。   The positioning adjustment of the second plate member 14 and the first plate member 15 with respect to the base 20 in the movable plate moving direction is performed without the case 11. First, a plate-shaped spacer having a predetermined thickness is inserted between the movable plate fourth plate portion 167 (see FIG. 6) and the first plate member 15 in the movable plate 16 through the notch portion 204. In FIG. 8, the portion where the spacer is inserted is indicated by hatching for convenience.

続いて、励磁コイル１２に通電して、可動板１６と第１板材１５との間にスペーサを挟持させるとともに、可動接点２５を第１固定接点２７および第２固定接点２９に当接させる。   Subsequently, the exciting coil 12 is energized to sandwich the spacer between the movable plate 16 and the first plate member 15, and the movable contact 25 is brought into contact with the first fixed contact 27 and the second fixed contact 29.

続いて、励磁コイル１２に通電したまま、第２板材１４を溝２０５内で通電遮断時移動向きＣに移動させて、第２板材１４や第１板材１５等をベース２０に対して通電遮断時移動向きＣに相対移動させる。   Subsequently, while energizing the exciting coil 12, the second plate member 14 is moved in the groove 205 in the movement direction C when the energization is interrupted, and the second plate member 14, the first plate member 15 and the like are energized with respect to the base 20. Relative movement is made in the movement direction C.

そして、可動接点２５が第１固定接点２７および第２固定接点２９から離れたところで、第２板材１４や第１板材１５等の移動を停止し、溝２０５内に接着剤を注入して、第２板材１４とベース２０との相対位置を決定する。   Then, when the movable contact 25 is separated from the first fixed contact 27 and the second fixed contact 29, the movement of the second plate member 14, the first plate member 15 and the like is stopped, the adhesive is injected into the groove 205, and the first The relative position between the two plate members 14 and the base 20 is determined.

続いて、励磁コイル１２への通電を遮断し、スペーサを切欠き部２０４を通して抜き出す。   Subsequently, the energization to the exciting coil 12 is cut off, and the spacer is extracted through the notch 204.

以上により、ベース２０に対する第２板材１４および第１板材１５の可動板移動方向の位置決め調整が完了する。   Thus, the positioning adjustment of the second plate member 14 and the first plate member 15 with respect to the base 20 in the moving plate moving direction is completed.

ここで、可動接点２５が第１固定接点２７および第２固定接点２９に当接してから可動板１６が第１板材１５に当接するまでの間の接圧ばね２４の圧縮量増加量は、スペーサの厚さと等しくなり、この位置決め調整により吸引完了時の接点圧力が精度よく調整される。   Here, the amount of increase in the compression amount of the contact pressure spring 24 from the time when the movable contact 25 contacts the first fixed contact 27 and the second fixed contact 29 to the time when the movable plate 16 contacts the first plate 15 is determined by the spacer With this positioning adjustment, the contact pressure at the completion of suction is adjusted with high accuracy.

（第２実施形態）
本発明の第２実施形態について、第１実施形態と異なる部分についてのみ説明する。図９に示すように、矩形平板状の第１板材１５には、ヨーク孔１５１から外縁まで連続する１つの切欠き部１５２が形成されている。 (Second Embodiment)

本実施形態の第１板材１５は１枚もので連続しているため、第１実施形態と同様に、電磁吸引力のばらつきが小さくなるとともに、電磁吸引力が増加する。   Since the first plate member 15 of the present embodiment is continuous with one sheet, similarly to the first embodiment, the variation of the electromagnetic attractive force is reduced and the electromagnetic attractive force is increased.
